Hi Gerald, sounds like ya got the PCV re-route done right. That other line is from the charcoal canister. The charcoal canister traps fuel vapors from fuel tank and releases (purges) them while engine is running. I don't see why you cant re-route that purge line from TB to air inlet also. If vacuum is present in the line during idle (check at the canister end), then re-routing will stop another "vacuum leak" and improve manifold vacuum stregnth. If there is a vacuum-controlled purge valve on the canister, it will be controlled by a small dia. line going to a manifold vac. source, and this smaller line needs to stay connected factory stock.
Quite a stack of wood ya got there, I wouldn't mind some of that for my brand new Rocket Oven. I test fired it 3 times to check it out, then baked a perfect loaf of bread in it 2 nights ago. I'm "chuffed" w/ it (as Rino would say!)
This thing is virtually unknown of, there is exactly ONE chap in England (I think) who has 3 vid's on youtube of his version, I shamelessly copied him. I have searched the Net, his is the only thing like it I can find.
Rocket Stoves are becoming popular though still un-known by the masses. 100's of vid's on Youtube. Many ways to make 'em and some commercial versions avail. Rocket OVEN though, nope ya gotta make your own, there's a few rocket Pizza ovens where flame/flue gasses contact or nearly so the food, plus Barrel meat smokers/BBQ's etc. But a wood fired oven w/ isolated oven chamber, that's about unheard of. Here's mine:
I've had it up to 550 deg. F! just to burn off residues, etc. It's a prototype, and needs a dedicated firebox still, right now it runs on a rocket stove thats got another rocket under it for a spacer, so looks odd. If I had some of your wood Gerald I would split it into kindling, that's all that's needed for fuel. Rocket Stoves are very fuel efficient, been running the Oven on sticks and twigs, 1" wide sticks are on the big side for this.
I know this has nothing to do w/ the Groove, though it is loosely related to fuel Efficiency!
